Hi,
I'm performing CFA with all binary variables. Which time of estimator do you recommend me to use ML or WLSMV? there is an specific estimator I should not use?

Thanks for your help

Maria

You can use either. If you have several factors, WLSMV is best because with ML each factor with binary factor indicators requires one dimension of integration. If you want to include residual covariances between factor indicators, WLSMV is also best because with ML each residual covariance requires one dimension of integration. Models using more than four dimensions of integration are not recommended.

Can you further explain what dimensions of integration are? Does this mean that I shouldn't run more than four factors within one CFA model at a time?

Numerical integration is discueed on pages 470-473 of the Version 7 user's guide.
